I saw this several months ago but missed the credits. The ghost or spirit of an Indian shaman comes back to life and kills a couple of people in a museum. The hero and heroine are trying to find him in the desert. The hero is also an Indian and keeps having flashbacks to his childhood and being terrified of seeing someone perform psychic surgery. I think he has to go to whoever was performing the surgery for help finding the spirit, but he doesn't want to because of the memories. Sorry I'm kind of vague on plot points but I didn't see all of it.

The film looked like 70s vintage but could have been very early 80s. Low budget for sure, and no one I recognized in it. Can you help?

Thanks! After looking up both films on the IMDB, I think that Ghost Dance is the one that I saw. The plot description and filming locations seem to match up with what I remember about it. Thanks again for the help.
